Title: Improvements in locking devices applicable to machine gun mountings
IPC: F41A23/00
Filed: 1942-09-28
Abstract: 560,383. Fastenings ; machine gun mountings. DARBY, D. Sept. 28, 1942, No. 13589. [Class 44] [Also in Group XXI] A fastening device particularly applicable to machine gun mountings and of the type in which a fixed jaw co-operates with a pivoted jaw to grip a part (such as the pin or trunnion 9 carried by the gun), the pivoted jaw being retained in fastening position by a sliding wedge or abutment, is provided with a handle-operated pivoted releasing device which withdraws the wedge and may also act on the pin 9 to eject it smartly when the wedge has been withdrawn. As shown, fixed jaws 3 are formed on spaced side-pieces 2 upstanding from a base I and the pivoted jaw 4 is, in known manner, in the form of a bell-crank lever having one arm 6 extending towards the fixed jaws so that insertion of pin 9 rocks the jaw to bring its other arm 5 into engagement with the pin. A sliding wedge or abutment 7 loaded by spring 8 engages under jaw 4 as shown to retain it in fastening position. Release is effected by a cam 13 on shaft 12 rotatable by handle 11. Interposed between cam 13 and pin 9 is an arm 10 pivoted on wedge 7 with its upper end bearing against pin 9 as shown. When cam 13 is rotated clockwise, Fig. 1, it urges arm 10 to the right. During the first part of the movement pin 9 remains immovable and acts as a fulcrum for arm 10, the pivoted lower end of which moves to the right and withdraws wedge 7 from engagement with arm 4 at the same time compressing spring 8. When the wedge is withdrawn leaving jaw 4 free to move arm 10 serves to eject pin 9 with smart action, rocking jaw 4 clockwise. As shown, base 1 is slidable along a support 15 against the action of a recoil spring 16. In a modification, the arm 10 is omitted and the sliding wedge is replaced by a pivoted two-arm lever, one arm of which-acts as a pawl or detent engaging a shoulder on jaw 4 to retain it in fastening position, the other end bearing against a spring plunger mounted on arm 6. The detent arm is acted on by a handle-operated pivoted cam which moves the detent clear of the shoulder and at the same time causes the other arm to compress the plunger spring so that, when the detent is clear, the spring rocks arm 4 clockwise, arm 6 directly ejecting pin 9.

Title: Numerical position control system
IPC: G05B19/31
Filed: 1963-04-05
Abstract: 1,035,431. Programmed control of machine tools. LICENTIA PATENT-VERWALTUNGSG.m.b.H. April 5,1963 [April 5, 1962], No. 13625/63. Heading G3N. In a numerical control system wherein an interpolator issues successive pulses representative of desired position values and a comparator compares the desired position values with actual position values to derive a deviation signal, a counter receives a train of auxiliary pulses and counts down from a set maximum value between interpolator pulses and an adder summates the residual count and the deviation signal and issues a signal to control a positioning motor. As shown, the output of a reader L is held in an intermediate store ZS and fed to an interpolator J providing a train of pulses B, B<SP>1</SP>, B<SP>11</SP>, representative of the calculated desired position values X k , to a comparator V having as the other input the signal from a measuring unit LM mounted on the machine table ST and sensing a digitally coded scale. A pulse generator, manually adjustable to a repetition rate equal to or higher than the interpolator pulse rate, supplies pulses through a frequency divider U to a counter Z counting down between interpolator pulses B, the residual count Xv being fed to a store 5 and through a gate T, opened by an error signal Xm from the comparator, to an adder A. The adder summates the residual count Xv and error signal Xw-and feeds this signal to a digital to analogue convector DA, determined in sign by a signal from the comparator V, controlling through an amplifier, a motor M driving the table ST.

Filed: 1975-04-03
Abstract: 1499592 Fluid pressure switches AUTOMATIC SWITCH CO 3 April 1975 13633/75 Heading H1N [Also in Division F2V] A fluid pressure controlled electric switch or fluid valve comprises a housing 12, 14, Fig. 2, supporting a micro-switch or valve 233 and actuator means 46, 111 extending to a detachable transducer assembly containing a sensing device such as a fluid diaphragm 32 which is retained in the transducer assembly when the assembly is detached. Each assembly comprises an end cap 119 with a fluid conduit connection 117 and is retained by a ring 26 held by screws 173 inserted in a flange 169 of the lower housing part 14. The fluid pressure diaphragm 32 is engaged between the end cap 119 and a flat plate 36 and is sealed by an O-ring 28 in a groove 137. Eyelets 153 rivet the plate 36 and ring 26 together to form the transducer assembly whereby it can be removed as a unit when the screws 173 are withdrawn. The plate 36 contains a piston 42 resting on the diaphragm 32 and engageable with a ball 70 on the underface of a balance plate 46 which is coupled to the switch actuating rod 111 and acts against a pair of return springs 76, 78 with adjustable settings whereby the response rate and differential between the switch operating positions may be varied. The plate 46 is generally triangular and rocks successively first about a pair of protrusions 51,  52, Fig. 12, against the action of the low pressure spring 76 and then about the protrusions 54, 56 against the high pressure spring 78. Threaded end caps 84, 86 accessible in an exterior recess of the housing adjust the load on the springs 76, 78 which rest on protrusions 88, 90 of differing height on the balance plate 46 whereby the springs 76, 78 can be adjusted to an equal load when flanges 98, 99 on the end caps 84, 86 are in abutment. The flanges 98, 99 are necessary to prevent the low and high pressure springs 76, 78 from being set in the reverse order. The pivot abutments 51, 52, 54, 56 rest on plates 60, 62 assembled in the housing by screws (74), Fig. 3 (not shown), and separated by a spacer ring 72. Plate 36 providing a cylinder for the piston 42 and supporting the diaphragm 32 is interchangeable with plates (36<SP>1</SP>), Fig. 9 (not shown), and 36<SP>11</SP>, Fig. 10, to provide for low or high pressure systems with a large or smaller piston. In the high pressure arrangement of Fig. 10 the plate 36<SP>11</SP> supports a small cylinder ring 278 above a small diaphragm 32<SP>11</SP> and O-ring 28<SP>11</SP>. A small piston 42<SP>11</SP> disposed within the cylinder ring 278 extends through an aperture 294 in the plate 36<SP>11</SP> to engage the ball 70.

Title: Pre-selective planetary variable-speed gearing
IPC: F16H61/02
Filed: 1933-05-12
Abstract: 419,220. Controlling brakes in planetary change-speed gearing. ALVIS CAR & ENGINEERING CO., Ltd., and CLARKE, G. T. SMITH-, Holyhead Road, Coventry. May 12, 1933, No. 13847. [Class 80 (ii).] Relates to planetary change-speed gearing for use on vehicles of the kind where a selected gear ratio is introduced by a friction clutch or brake applied by a take-up spring. The take-up spring is relatively light, applying, say, one quarter of the force required, and fluid pressure is afterwards applied to provide the remainder of the engaging force. As applied to a Wilson gear box, a strut 13, Fig. 1, preselected manually by cams has been thrust into the path of a bus-bar 14 as it rises. This bar 14 has been thrust down by a stroke of a main control pedal through a lever 33 which depresses the left end of a lever 19 engaging a raised portion 21 of the bar. This stroke compresses a take-up spring 18 such as is described in Specification 408,248. The drive is now disengaged. Hitherto, when the executive control pedal has been released, the full force of the spring 18 has become operative after the bar 14 has risen past alignment with a link 16, causing " snatch " in the drive. According to this invention, the take-up spring is replaced by a lighter one and this spring 18 instead of acting directly on a connecting lever 17, bears against an interposed piston 22 slidable in a cylinder 23 which is at all times open at 24, Fig. 2, to a source of oil pressure. Preferably such source is a pump 25 constantly driven from the driving-shaft 26 of the gearing. The first part of the depression of the main control 33, Fig. 1, by depressing the lever end 19, Fig. 2, vents the cylinder 23 at 29 so that the oil pressure vanishes. Consequently it is only at the end of the rise of the main control pedal, which rise is not unduly violent, that the valve 29 is closed whereby oil pressure building up in the cylinder 23 thrusts the piston 22, Fig. 1, strongly to the right, and, through the toggles shown, applies the brake 12 powerfully to its drum. Specification 402,794 also is referred to. According to the Provisional Specification, air pressure may be used instead of oil pressure.
